reissue filed April 17,,1922. Serial 110.654340}.

T 0 all w ham it may concern Be it known that I, ELMER E. THRA-SI-IER.

a citizen of the United States of America,

residing at South Cumberland, in the county of Allegany and State ofMaryland, have invented certain new and useful lmprovements in Attachersand Automatlc Sealers for Camera Films, of which the following I is aspecification.

The usual manner of attaching the freed end of a film strip for windingwhen the spool as shown in Fig. 2 isinitially placed in a camera, suchas folding camera, is more or less inconvenient and liable to mistake onthe part of an inexperienced operator and one object of myinvention isthe provision of a ready means for attaching the end of the film stripcorrectly to the winding spool without the possibility of a mistake andbefore the strip is unsealed thereby permitting the closing of thecamera for subsequently winding the spool, automatically unsealing thestrip and starting the winding operation for the successive exposure ofthe proper film. surface portions.

In connection with the automatic unsealing of the film strip in theclosed camera my invention includes a substantially reversely operatingautomatic initial sealing or closure retainer for the film strip afterentire exposure has taken place insuring the perfect condition of theexposed film when'the camera is opened and the filled spool removed fordeveloping.

By means of my invention, the slipping and spoiling of a film isprevented as well as a foot or more of the heavy paper film -windingstrip saved.

With these general objects in view and that of saving expense as well asannoyance in operating the camera, my invention which is easy andinexpensive to manufacture and readily applied to any film camera.

having a spool winding means, the invention consists of the novelcombination and arrangement of parts hereinafter more fully described,illustrated in the accompanying drawings and then claimed.

In'the drawings, forming apart of this application and in which likereference characters designate correspondingparts throughout the severalviewsgv Figure 1 is a rear elevational. camera with the lid removed withthe sealed spool -offilm in its proper place at the unwindlng end of thecamera.

Figure 2 is a similar view of the unwinding end portion of the camerawith the atv taching cord par'tially released for securing to thewinding spool atthe opposite end thereof.

Figure 3.is a view similar to Figure 1 showing the manner ofautomatically breaking the seal, the lid being preferably closed duingsuch operation.

Figure 4 shows a further step in the unwinding operation after the sealis broken.

Figure 5 is a detail sectional view taken upon line, VV of Fig. 1.

Figure 6 shows the opposite end portion of the film strip and theholding cord attached thereto.

Figure 7 is an elevational view of the unwinding end of the camerashowing the anchoring cord secured in one manner to the deliveringspool.

Figure 8 is an elevational view of one of the spools with the centralportion illustrated in longitudinal section.

Figure 9 is an elevational view of the receiving spool with the filmstrip completely rolled thereon and the anchoring cord overlying thesame, and

Figure 10 is an inverted view similar to Figure 9 with the adhesivestrip finally closing the film roll and holding the cord .in'place.

My inventionbeing serviceable in a film camera 10., herein illustrated,is employed with the long paper film strip 11 wound upon the deliveryspool 12 when originally --purchased, for insertion-in one end portionor compartment 13 of the camera for winding upon the receiving spool 14in the opposite end compartment '15,. the winding key 16 being providedtherefor.

. Both ofthe spools-12 andl l are provided substantially centrally witha cord-receiving groovel? and a perforation 18 for attaching thereto oneend of a cord, and anchoring ears 19 are struck up from the spool, sothat either the perforation or the ears may be employed for securing thecord to the spool.
